The Diagnostic Value Of Mir-145 And Mir-205 In Patients With Cervical Cancer
AMERICAN JOURNAL OF TRANSLATIONAL RESEARCH(2021)
Abstract
Objective: To investigate the diagnostic value of miRNA-145 (miR-145) and miRNA-205 (miR-205) in cervical cancer patients. Methods: Cervical tissue samples were collected from 144 patients diagnosed with and suspected to have cervical cancer in our hospital. Confirmed by pathology, 84 samples were obtained from cervical cancer patients and 60 samples were from patients with cervical intraepithelial neoplasia. Meanwhile, 30 patients with cervicitis were also selected, and the expression levels of miR-145, miR-205 and human papillomavirus (HPV) were detected in cervical lesions and normal cervical tissue. Results: In comparison to normal cervical tissue, cervicitis and cervical intraepithelial neoplasia groups, the relative expression level of miR-145 was significantly lower, whereas the relative expression level of miR-205 was notably higher in the cervical cancer group, respectively (P<0.001). The area under the receiver operating characteristic (ROC) curve of miR-145 for diagnosis of cervical cancer in patients was 0.878, of which the sensitivity and the specificity were 0.905 and 0.822, respectively. The area under the ROC curve of miR-205 was 0.881, of which the sensitivity and the specificity was 0.869 and 0.889, respectively. Among all patients, the relative expression level of miR-145 was significantly lower while the relative expression level of miR-205 was considerably higher in HPV-positive patients than those of HPV-negative groups (P<0.001). Parauterine invasion, FIGO stage III-IV and lymphatic metastasis were considered as independent factors that affect the expression of miR-145. FIGO stage III-IV and lymphatic metastasis were independent factors affecting the expression of miR-205. Conclusion: The low expression level of miR-145 and the high expression level of miR-205 in patients with cervical cancer demonstrate a certain diagnostic value in cervical cancer. The expression level of miR-145 and miR-205 is correlated with HPV infection and cervical tumor malignancy.
